[jira] [Commented] (FLINK-3419) Drop partitionByHash from DataStream

    [ https://issues.apache.org/jira/browse/FLINK-3419?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15149257#comment-15149257 ] 

Stephan Ewen commented on FLINK-3419:
-------------------------------------

+1 from my side

It seems it can do nothing that {{keyBy()}} would not do either, and it adds clutter to the API.

> The behavior is no different from {{keyBy}}, except that you cannot use keyed state and windows if you use {{partitionByHash}} so I suggest to drop it.
> We might also want to think about dropping {{shuffle}} and {{global}}.
